Description
- The present invention refers to an ice-crusher which can be used either at home or professionally and be useful in kitchens, hotels, restaurants, guesthouses and communities in general.
- At present a great number of domestic and industrial apparatus is available which can be used to prepare and treat foods, e.g. beaters, blenders, slicers, meat choppers, juicers, mixers, etc.
- In time, these apparatus have become more and more versatile and reliable, in particular with regard to the possibility of carrying out several operations with one multifunction device.
- However, most tools used in apparatus for preparing and treating foods do not provide optimum functionality.
- For example, in the case of ice-crushers, conventional apparatus usually comprise a grinding hole made of melted aluminium, the hopper of the grinding hole including a semicircle feeding collar to the top of which a lever is hinged which pushes ice towards a cutting unit. The cutting unit includes a rotating disc to which a cutting blade is attached, said cutting blade being integral with a driving shaft horizontally positioned relative to the machine, whereas the product is released through an opening at the bottom of the grinding hole.
- However, prior art devices do not permit to grind ice with different kinds of thickness, consistency and size, as requested in the last few years on the market; as known, the request is getting more and more widespread to use one single device to break up ice into pieces of different size and thickness, from the most small pieces (mainly requested to prepare water-ice) to the thickest and most consistent pieces (particularly used to prepare cocktails and to present some products and courses, such as those based on fresh fish).
- Therefore, the general object of the present invention is to solve the above mentioned technical problems of prior art devices in a new, extremely simple, cheap and particularly functional way. In particular, the object of the invention is to provide an ice-crusher which permits to break up ice into pieces of different size and thickness by using a single tool.
- Another object of the present invention is to provide an ice-crusher which permits to protect the drive motor against the possible seepage of water from the cutting unit and against the mechanical stresses produced by the ice blocks being ground, which usually compromise the normal motor life.
- A further object of the present invention is to provide a particularly effective, handy and safe ice-crusher which, due to the achieved advantages, is extremely small and involves considerably reduced production costs relative to conventional ice-crushers.
- These and other objects are provided by means of an ice-crusher according to claim 1, which is referred to for the sake of brevity; other technical features of the apparatus are set out in the alleged dependent claims.
- The structural and functional features of the present invention and the advantages thereof with respect to prior art will become even clearer from the following description, with reference to the accompanying drawings, in which:
-
figure 1 shows a first axonometric view of the ice-crusher according to the present invention; -
figure 2 is a second axonometric view of the ice-crusher according to the present invention; -
figure 3 is a rear view of the ice-crusher according to the present invention; -
figure 4 is a sectional view taken along line IV-IV offigure 3 ; -
figure 5 is an axonometric cross-sectional view of the ice-crusher according to the present invention; -
figure 6 shows an enlarged view of a detail offigure 5 ; -
figure 7 is a schematic side view of the cutting unit used in the ice-crusher according to the present invention; -
figure 8 is a sectional view taken along line VIII-VIII offigure 7 . - With reference to the drawings, the whole ice-crusher is indicated with
numeral 10 and it comprises afront portion 11 for inserting ice and collecting the ice pieces and arear portion 12 consisting of ashaped covering 13 for an area containing the cutting unit and the motor driving such a unit. - A
switch 14 for putting theapparatus 10 on and off is placed on thecovering 13, said covering 13 resting on ashaped base 41 which absorbs the mechanical stresses transmitted by theapparatus 10 while working. - The
front portion 11 of the ice-crusher 10 comprises agrinding hole 15, normally made of melted aluminium, into which the ice (usually in the shape of cubes of various sizes) to be ground is inserted. - The hopper of the
grinding hole 15 consists of asemicircle feeding collar 16 onto to the top of which alever 18 is hinged by means of ablock 17. Saidlever 18 is provided with ashaped handle 19 which, through the motion of ashaped plate 22, permits to push the ice into the cutting unit (which is provided inside the ice-crusher 10 and is described in detail below). - The
lever 18 is interlocked with amicroswitch 20 which prevents the user from approaching the inner grinding unit while the motor of the ice-crusher 10 is working. - The ice being broken into pieces of different thickness, consistency and size is released through an opening at the
bottom 21 of thegrinding hole 15 which, in prior embodiments of the ice-crusher 10, is provided with a protection grid to prevent the user from inserting the user's fingers into the working area. - With reference to
figures 4-8 , which show the construction details of the ice-crusher 10 of the invention, the ice cutting unit includes a rotatingdisc 23 to which acutting blade 25 is attached by means of a fasteningscrew 24, saidcutting blade 25 being integral with adriving shaft 26. - In particular, the above mentioned cutting unit comprises a
flange 27 supporting thedriving shaft 26 on which a plurality ofbearings 28 is attached which are serially set up ontorespective spacers seal rings - The
bearings 28 are set up adjacent to thedriving shaft 26, while thedisc 23 rotates integrally with theshaft 26 by inserting one or morecylindrical plug 33. - According to the present invention, the distance of the rotating
disc 23 from theblade 25 can be axially adjusted by the user simply by means of a key, without having to open the covering 13 of the ice-crusher 10. - In this regard, a
horizontal motor 34 is provided inside the covering 13, saidmotor 34 being staggered relative to the working and/or drivingshaft 26. Thehorizontal motor 34 also transmits motion to the rotatingdisc 23 by means of abelt 39, thus leaving room, on the upper portion and opposite thecutting blade 25, inside the covering 13 of the ice-crusher 10 for the user to operate on the device for regulating the thickness of the ground ice. - Such a regulating device comprises, in particular, a
ring nut 35 locking the pulley of thedriving shaft 26. Inside said ring nut 35 athickness regulation screw 36 is provided which is integral with thedriving shaft 26 and with athickness regulation bush 37 which is adjacent to thecutting blade 25. - The operator can thus act on the
screw 36 by means of a key from outside the covering 13 to regulate axially the distance of thedisc 23 from theblade 25. - Such an operation can be easily carried out by the user due to the presence of the
hole 38 on the covering 13 axially with respect to theregulation screw 36. - This arrangement also protects the
motor 34 against the possible seepage of water from the cutting unit and against the mechanical stresses produced by the ice pieces being ground, which would compromise the motor life. - Finally, the rev reduction of the
motor 34 on the drivingshaft 26 by means of thebelt 39 also permits to employ a manifold motor 34 (not an induction motor, as in conventional ice-crushers), with considerable operating advantages, such as a high number of revolutions (therefore, the rev reduction increases the torque transmitted to thedriving shaft 26, thus increasing the effectiveness thereof), better self-cooling (for an even harder use of the motor 34), reduced dimensions as well as production and operating costs. - According to the invention, in the ice release area corresponding to the
lower portion 21 of the feeding hole 15 acup 40 is provided to collect the crushed product, such a cup also being interlocked with a microswitch, so that, by removing the cup, the ice-crusher 10, if turned on, automatically stops. - The use of the collecting
cup 40 helps to release ice which, otherwise (as in conventional ice-crushers), tends to get stuck in the protection grid which is placed adjacent to thelower portion 21 of thehole 15. The characteristics of the ice-crusher of the present invention, as well as the advantages thereof become apparent from the above description. - Anyway, it is clear that several variations can be made to the ice-crusher of the invention, without thereby departing from the scope of the invention as defined in the claims, and that, when practically carrying out the invention, the materials, shapes and dimensions of the illustrated details can vary according to the user's needs and be changed with other technically equivalent ones.
